1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Artificial intelligence (AI) compute demands outstrip electronic hardware scaling, creating a critical "AI compute gap." Photonic computing promises speed, low latency, and parallelism yet faces bottlenecks in core array scalability and optoelectronic bandwidth efficiency. We propose a time-domain parallelism (TDP) computing architecture that temporally multiplexes compact cores, enabling large-scale convolutional operations while optimizing bandwidth efficiency. Supporting this framework, we develop indium tin oxide (ITO)-based photonic devices demonstrating a record 9-bit dynamic reconfigurability at 60 kilohertz and a 3-decibel bandwidth of 311 kilohertz. These devices feature compact phase shifter lengths (
